Guru3d is reporting an issue with the GTX 1070 and GTX 1080. They report that you may have issues booting into windows if you have a monitor refresh rate of greater than 81hz AND are using the DVI port. The temporary fix is to just use Display Port or boot into windows safe mode and switch the refresh rate to 60hz or below 81hz. Click the photo or source link for their full repot.
Well as the title says; PCPer reported the news recently that Nvidia changed their minds and will not support 3 and 4 way SLI for gaming. They will enable it for certain benchmarks though. In all honesty though this is not really an issue as the performance gains above 2 cards is minimal. Check the video for the details.
Jay explains the truth behind the false rumors of Pascal only being able to do 2 way SLI. Basically you can do 3-4 way but will need a key from Nvidia. Nvidia technically only supports 2 way now but they are not locking you out of more cards. Click the video and give Jay a follow!
